Undoubtedly this streak is unusual (as much as I'm enjoying it
). I would posit, however, that the streak of ugliness that started the season was likewise unusual, despite some folks proposing sweeping conclusions otherwise (to borrow your SH% example, recall how ludicrously low the team's shooting percentage was earlier in the season). We're seeing the happy side of regression to the mean. We're probably not regularly as good as we're showing right now, but we weren't as bad as we looked in October and November either.
